It is understood that the working capital is sufficient for the current requirements, as well as the resources from cash and loans from third parties, are sufficient to meet the financing of its activities. The Board of Executive Officers of TIM S.A. also believes that the Company has the capacity to take out loans to finance its activities, if necessary. The liquidity ratios, which indicate the company's financial capacity to honor its commitments to third parties, present controlled levels compatible with the strategic moves adopted by the Company, as shown in the table below. In addition, other indicators are used to measure the coverage of financial expenses and gross debt and both point to a comfortable situation of the Company, as reported below: Leverage Ratio 2025 In thousand reais Gross Debt 16.026 Shareholders' Equity 23.977 Gross Debt / Shareholders' Equity 66,8% Capital Structure Ratios 2025 General Indebtedness (Current Liabilities + Non-Current Liabilities)/ Total Liabilities 57,9% Composition of Indebtedness (Current liabilities /(Current liabilities + Non-Current liabilities)) 46,1% Liquidity Ratios 2025 Immediate liquidity (Cash and Cash Equivalents and Marketable Securities/Current liabilities) 38,9% Current Liquidity (Current Asset/Current liabilities) 88,6% Quick Ratio ((Current Asset-Stock)/Current liabilities) 86,2% Classified as Public • Adjusted EBITDA in 2025 totaled R$13,529 million, while net financial income represented net financial expenses of R$1,784 million in that year and gross debt was R$16,026 million as of December 31, 2025.

Sources of financing for working capital and investments in non-current assets used The Company's main source of financing in its last fiscal years is the generation of operating cash, complemented by short-term credit lines with local and international banks and long-term financing with national and international development agencies. The Executive Board understands that such sources of financing are appropriate to the Company's indebtedness profile, meeting the needs of working capital and investments, always preserving the Company's ability to pay.

The cost of this line is IPCA plus interest of up to 2.84% per year + spread according to the term. We disbursed 100% of the line in November 2021 with a cost of IPCA + 4.2283% p.a. and a term of 10 years. This debt is fully protected by swap with a posthedge cost of 96.95% of the CDI.

Significant changes in items on the income and cash flow statements General Analysis of the Result Net Revenue In 2025, Total Net Revenue and Services Revenue increased by 4.6% YoY and 5.2% YoY, respectively, driven by the solid performance of Mobile Services revenue in 2025, outperforming inflation in 2025 (IPCA 2025: 4.26%).

Directors should comment: a. results of the issuer's operations, in particular: i. Description of any important components of the recipe The Company generates its revenues in local currency, from the provision of telecommunications services with mobile, fixed, and ultra-broadband telephony, in addition to value-added services, which also include data transmission. Another component of the revenue is the use of network or interconnection revenue, which comes from the amount charged to other operators for the termination of traffic on the TIM S.A. network. Product revenue is also part of the revenue group, referring to the sale of cell phones, accessories and others. ii. factors that materially affected operating results Considering that TIM S.A. has more than 90% of its revenues produced by customers of mobile telephony services, the main operational element that affects the results of this company is the dynamics of the mobile access base. b. material changes in revenues attributable to the introduction of new products and services, changes in volumes and changes in prices, exchange rates and inflation The Company's revenue is basically composed of local currency, thus not being affected by possible exchange rate variations. It is directly impacted by changes in its customer base, 2025 In million reais Net cash generated by operating activities 1 3.440 Net cash applied on investment activities (3.561) Net cash applied in financing activities (9.528) Cash and cash equivalents at the beginning of the financial period 3.259 Cash and cash equivalents at the end of the year 3.610 DESCRIPTION Classified as Public variations in the volume of use and modifications in the rates charged due to a new tariff plan, product launch or introduction of promotions. The Company may adjust the prices of its tariff to the public as long as they are included in the limit price approved by ANATEL, the maximum amount is subject to an annual adjustment according to the behavior of inflation. In many cases, although ANATEL allows readjustments, the strong competition in the sector leads to reductions in the tariffs charged. c. relevant impacts of inflation, price variation of the main inputs and products, exchange rate and interest rate on the operating result and financial result of the issuer Inflation: Possible increases in the inflation rate may lead to higher costs for the Company and consequently a reduction in margins. In the event of a strong inflationary scenario, the government may adopt a more austere monetary policy, such as increasing interest rates, reducing and making the supply of credit more expensive and, consequently, affecting our consumers of telecommunications services. Interest rates: The Company's financial expenses are affected by fluctuations in the CDI (Interbank Depositary Certificate). The Company maintains its financial resources invested mainly in Interbank Certificates of Deposit (CDI), which substantially reduces this risk. Exchange rate: As mentioned in item 2.2 sub-item "b", the Company's revenue is basically composed of local currency, thus not being affected by possible exchange rate variations. With respect to the financial result, as mentioned in item 2.1 sub-item "b", the company has swap operations, with the objective of protecting itself from the risks of exchange rate variation and rates in its loan and financing operations. 2.3.

Describe the statutory clauses that determined the reserve Paragraph 2 of Article 46 of our Bylaws reads as follows: “The balance of net profit not allocated to the payment of the mandatory minimum dividend will be allocated to a supplementary reserve for the expansion of the company’s businesses, including, without limitation: investments in infrastructure and in the development of products and services. The reserve provided for in this Paragraph 2 cannot exceed 80% of the share capital. Reaching this limit, it will be up to the General Meeting to decide on the balance, distributing it to shareholders or increasing share capital.” b. Identify the amount allocated to the reserve As mentioned above, up to the limit of 80% of the share capital, all amounts not allocated to the minimum mandatory dividend or proposed dividends may be allocated to this reserve. In 2025, the Company used reserves from previous years to approve interim dividends of four hundred ten million, eight hundred six thousand six hundred fourteen reais and thirty-eight centavos (R$ 410,806,614.38) and interest on shareholders’ equity of four hundred ninety million (R$ 490,000,000.00).

Classificado como Público The Company conducted an express verification of the statutory limit, confirming that the closing balance of the Expansion Reserve remains below 80% of the share capital in effect on December 31, 2025, with no excess to be reversed or distributed. Thus, the proposed allocation is in accordance with the Bylaws, Law 6404/76, and CVM Resolution 81 c.

Compensation Proposal for the Company’s Administrators and Fiscal Council members for the year of 2026 Classificado como Público COMPENSATION PROPOSAL OF THE MANAGEMENT AND FISCAL COUNCIL The process of preparing the Compensation Proposal for Management and the Fiscal Council presented below was supported by market compensation studies, prepared by a renowned specialized consulting firm, with an overview of market practice in general and in selected markets, considering companies with characteristics, size, and governance levels similar to those of the Company. The evolutionary assumptions adopted for the preparation of this proposal were defined with the main objectives of aligning the compensation of managers with the best practices identified in the market study and supporting the achievement of the Company's strategic objectives. Therefore, according to the proposal presented to the Compensation Committee and to the Board of Directors of TIM S.A. ("Company"), in meetings held on February 25th, 2026, the following compensation will be proposed to the General Meeting: 1) Board of Directors: Proposal for a total annual compensation of R$ 4,860,000.00 (four million, eight hundred and sixty thousand Reais). The proposed amount provides for the maintenance of the practices and values approved for the previous year. 2) Fiscal Council: Proposal for total annual compensation of R$ 702,000.00 (seven hundred and two thousand reais). The proposed amount provides for the maintenance of the practices and values approved for the previous year. 3) Statutory Officers: Proposal for an annual global remuneration of R$ 47,498,000.00 (forty-seven million, four hundred and ninety-eight thousand reais). For the Fixed Remuneration component, it is planned to review the amounts currently practiced, considering the forecasts of wage growth in the market and inflation, resulting in a proposal with a total average increase of 5.8% compared to the proposal approved in the previous year. The proposal regarding the Short-Term Variable Compensation considers the most optimistic scenario in relation to exceeding the objectives established for the program's performance indicators, as provided for in the Company's policy. For the proposal of Long-Term Variable Compensation, the amounts referring to the grants already granted and the realization of a new grant were considered, in accordance with the regulations and resolutions of the Board of Directors. Despite the maintenance of the current Classificado como Público award policy of the Long-Term Incentive Plan, the proposal for 2026 shows a growth of 5.6% compared to that approved for the previous year, mainly due to the revisions of the award policy that applied in 2023, 2024 and 2026, since the accounting for each grant occurs during the vesting period, which can last up to 3 years. For the Benefits component, the proposed amounts reflect the adjustments resulting from inflation indices and current contractual conditions. And, finally, an additional amount was proposed providing for expenses with terminations and/or hiring, in case of any changes in the current composition of the Board of Executive Officers. Therefore, the amount of compensation presented here, provides for an increase of 2.6% in the compensation approved for the previous year. If we do not consider the accounting adjustments for the long-term incentive, the total change from 2026 vs 2025 would be zero. 4) Committees Proposal for a total annual compensation of R$ 3,024,000.00 (three million and twenty-four thousand reais). The proposed amount provides for the maintenance of the practices and values approved for the previous year. Classificado Classificadcoo mcoom Uos oP úInbtleicrnoo 8. Item 8 from the Reference Form Classified as Public 8.1. Describe the policy or practice for compensation of the board of directors, of the statutory and non-statutory executive boards, of the fiscal council, statutory committees and audit committees, for risk, finance and compensation, covering the following aspects: a. objectives of the compensation policy or practice, informing whether the compensation policy was formally approved, the body responsible for its approval, date of approval and, if the issuer publishes the policy, locations on the world wide web where the document can be consulted The TIM S.A. Management Compensation Policy approved by the Board of Directors on December 15, 2021 (available on the Company’s Investor Relations website) is an instrument that aims to establish the rules and principles for defining and evolving the compensation of members of the Board of Directors, Advisory Committees, Fiscal Council and Statutory Executive Board in an aligned and competitive manner with market practices, aiming to attract, engage, recognize and retain the human resources required to achieve the Company’s strategic objectives, always respecting the corporate governance requirements for publicly traded companies within the country. The resulting compensation architecture must balance compensation (fixed and variable) and leverage the benefits system, aiming at generating long-term sustainable results for TIM S.A. The definition of the compensation structure and values is supported by the analysis of market practices, mainly in the high technology and telecommunications market, as well as companies that are similar in size and governance characteristics (they are part of the Novo Mercado [New Market], listed on the New York Stock Exchange, etc.) and is updated annually according to the market movements and the Company’s strategic planning. The methodology provides for analysis of the compensation practiced by the market (whether fixed, variable, benefits or compensation for participation in committees), considering benchmark companies and surveys provided by companies specialized in compensation, such as: Korn Ferry Hay Group, Willis Towers Watson, among others. Comparisons consider the different available statistics (median and 3rd quartile). The compensation breakdown considers the importance of the occupant’s role within the organizational structure, based on the Total Compensation market parameters, identified in specialized market surveys. The elements of Fixed Compensation, Variable Compensation and Benefits are weighted by assessing the grade and matching positions. In the TIM S.A. organizational structure, and in accordance with the Internal Regulations of the Board of Directors approved on July 29, 2020 and updated on September 28, 2020, there is a specific committee to address the compensation of the Company’s Management, which is the Compensation Committee, composed of 3 effective members of the Board of Directors.

Comparisons consider the different available statistics (median and 3rd quartile). Classified as Public The compensation breakdown considers the importance of the occupant’s role within the organizational structure, based on the Total Compensation market parameters, identified in specialized market surveys. The elements of Fixed Compensation, Variable Compensation and Benefits are weighted by assessing the grade and matching positions. iii. how often and how does the board of directors assess the adequacy of the issuer’s compensation policy TIM S.A. has its Compensation Practices (Long-Term Incentive Plan, Short-Term Incentive Program – MBO (Management By Objectives), and Management Compensation) approved annually by the Board of Directors, after being examined and recommended by the Compensation Committee. c. breakdown of compensation, indicating: i. description of the several elements that make up the compensation, including, in relation to each of them: • its objectives and alignment with the issuer’s short, medium and long-term interests The Compensation of the members of the Board of Directors and the Fiscal Council is composed of a single element, which is the Fixed Compensation, which may be complemented by participation in advisory committees. The fixed component aims to enhance the strategic role of the members, having as a benchmark the values practiced in the market. In turn, the Compensation of the Statutory and Non-Statutory Executive Board is composed of 3 elements: Fixed Compensation, Variable Compensation and Direct and Indirect Benefits, with varying degrees of relevance, due to market practices, the Company’s positioning and the objectives for the position. Each component is duly detailed below: 1) Fixed Compensation: It aims to recognize and reflect the breadth of scope and value of the position internally and externally, as well as the individual performance, experience, education and knowledge of the executive, supported by market practices. 2) Variable compensation: Aims to reward the achievement and surpassing of the Company’s goals, aligned with the budget, strategic planning and market practices. Through this instrument, the aim is to achieve / exceed the targets and objectives of the organization defined in the three-year industrial plan presented to the market. In turn, the variable component is broken down into four groups, namely: 2.1) MBO The MBO – Management By Objectives – is the short-term variable compensation program, based on the concept of profit sharing, linked to strategic indicators for the Company’s business, containing goals and corporate objectives. - Corporate Objectives: the Company’s macro objectives, with high strategic relevance, which depend on the collective efforts of all the Company’s employees to be achieved. The performance indicators that are considered in determining the corporate objectives of the incentive plan are the main financial and operational indicators and ESG indicators (such as Employee Engagement, Renewable Electric Energy, among others), reassessed and validated annually, always in line with the objectives presented to shareholders for the Triennial Plan. Classified as Public Such objectives are proposed annually by the Company’s management in accordance with the challenges of the Industrial Plan, and approved by the Board of Directors, upon recommendation of the Compensation Committee. 2.2) Bonus (una tantum) The Bonus is an instrument based on valuing individual performance, which can be used to recognize the outstanding performance of the executive, as well as rewarding the results of specific and relevant initiatives and projects for the Company. 2.3) Hiring/Retention Bonus The Company, when analyzing the market conditions, context and challenges of the business and aiming to guarantee the continuity of the business and compliance with the strategic plan, can offer the payment of specific bonuses to ensure the hiring and / or retention of key executives. In the specific case of Hiring Bonuses, this modality aims to make it possible to make offers that are more attractive to external candidates and that minimize any occasional losses that may exist in the transition between companies. 2.4) Long-Term Incentive Plan: In recent years, the Company has instituted share-based incentive plans for senior managers and those employees who hold key positions in the Company. Such a long-term mechanism aims to: (i) align the interests of senior management with the interests of shareholders, through participation in the business risk; (ii) implement an integrated incentive system, aiming to balance the time horizon and the nature of the objectives; (iii) increase the competitiveness of the recognition package and (iv) operate as an instrument for retaining key people for the Company. It is worth highlighting that the Company has a Securities Disclosure and Trading Policy, pursuant to CVM Resolution 44/21, which is communicated to each new member elected in the Company’s senior management upon signature of the Term of Adhesion, which is filed at the Company’s headquarters. The Long-Term Incentive Plans establish general terms and conditions for the granting of Company’s shares, by senior managers and those employees who hold key positions in the Company, as approved by the Board of Directors and recommended by the Compensation Committee, based on proposal by the Chief Executive Officer and the People, Culture & Organization Officer. The Plan’s management is incumbent upon the Board of Directors, which may delegate the assignments specified to the Compensation Committee, subject to the terms of the Plan and the limits provided for by law and in the Company’s Bylaws. The Board of Directors is entitled to: - decide on any measures related to the management of the Plan, interpretation, detailing and application of the general rules established herein; - modify the terms and conditions for granting the Shares, with the purpose of adapting them to any requirements that may become necessary due to any legal or regulatory changes applicable to the Plan or the Stock Granting Agreement; - decide on omitted cases, following the general guidelines of the Plan and the applicable legal provisions; - analyze exceptional cases related to the Plan; - select the Participants, at its sole discretion, previously evaluated by the Human Resources Board and by the Chief Executive Officer and examined by the Compensation Committee; - authorize the Company’s Board to sign the Stock Granting Agreements with the Plan Participants; and - in case of exceptional situations that make it impossible for the Plan to continue, create mechanisms and rules and/or modify the terms of the Stock Granting Agreement, including replacing it with similar Classified as Public instruments, aiming to avoid any distortions and losses to the Participants, to the Company and its Shareholders, in strict alignment with the Plan’s objectives. The Board of Directors must refrain from, except for the adjustments expressly permitted by the Plan: (i) increasing the total limit of Shares that may be granted under the Plan; (ii) changing the provisions relating to the eligibility of Participants; or (iii) without the holder’s consent, modifying or impairing any rights or obligations arising from Stock Granting Agreements entered into with any Participants. 3) Direct and indirect benefits: It aims to offer products and services that increase the well-being of the individual and his/her family in economic and social terms, reflecting on the value received by executives, aiming to attract and retain them in the Company. The benefits package for each member of Senior Management considers the importance of the occupant’s role within the organizational structure, based on the Total Compensation market parameters identified in specialized market surveys. The Company seeks to offer a comprehensive benefits package for Senior Management that manages to cover the different dimensions of well-being, with eligibility criteria that can be specific or related to the grade and position of the holder. Benefits evolve according to market practices and the collective agreement, as well as the evolution of people’s expectations and needs. Some examples of benefits offered by the Company are: private pension plan, extended maternity, paternity and marriage leave, health care plan, dental plan, life insurance, day care assistance and food/meal vouchers. The Company also offers executives the opportunity to customize their benefits package in a way that best meets their needs through a flexible benefits platform. ii. in relation to the last 3 fiscal years, what is the proportion of each element in the total compensation calculation methodology and readjustment of each of the compensation elements. Fiscal Year 2025 (Actual) Board of Directors Fiscal Council Statutory Executive Board Non-Statutory Executive Board Number of effective members 4.25 3.0 6.25 0.0 Fixed compensation (%) 100% 100% 28,0% N/A Variable compensation (%) 0% 0% 32,8% N/A % Share-Based Compensation (including options) 0% 0% 39,2% N/A Fiscal Year 2024 (Actual) Board of Directors Fiscal Council Statutory Executive Board Non-Statutory Executive Board Number of effective members 5.0 3.0 6.0 0.0 Fixed compensation (%) 100% 100% 28.9% N/A Variable compensation (%) 0% 0% 22.6% N/A % Share-Based Compensation (including options) 0% 0% 48.5% N/A Fiscal Year 2023 (Actual) Board of Directors Fiscal Council Statutory Executive Board Non-Statutory Executive Board Number of effective members 5.0 3.0 6.4 0.0 Fixed compensation (%) 100% 100% 41% N/A Variable compensation (%) 0% 0% 27% N/A % Share-Based Compensation (including options) 0% 0% 32% N/A • its calculation and readjustment methodology Classified as Public The compensation structure aims to follow market practices, mainly in the high technology and telecommunications markets, as well as companies of similar size and governance characteristics (they are part of the Novo Mercado [New Market], listed on the New York Stock Exchange, etc.) and is updated annually according to the market movements and the Company’s strategic planning. The compensation of the Board of Directors, the Advisory Committees and the Fiscal Council are revisited annually, through comparative analysis with market practices, supported by specialized research. Based on the result of these analyses, a compensation adjustment is proposed or not, which is first presented to the Compensation Committee that, after its evaluation, recommends the adjustment to the Board of Directors, always respecting the maximum limits approved at the Shareholders’ Meeting. The Compensation of the Executive Board is made up of the following elements, with varying degrees of relevance, due to the impacts they may generate on the Company’s results. According to the introduction, the organizational evaluation of positions and compensation amounts is made through an internal system that classifies positions in “bands” based on the Hay methodology (system with which the main positions of the organization are evaluated). Through this methodology, the Company facilitates the comparison of its position with the market, in addition to supporting the management and development of human resources. Thus, it is possible to recognize and reflect the breadth of scope and value of the position internally and externally, as well as the individual performance, experience, education and knowledge of the executive, supported by market practices. 1) Fixed compensation Base Salary or Management Fees: The fixed compensation consists of the payment of 12 installments per year, plus the 13th salary and vacation for senior executives who are governed by the Brazilian Labor Code (CLT). The definition of the benchmark fixed compensation to support the definition of the individual compensation of each member of the Executive Board is based on the “weight” of the position, according to the Hay methodology. The definition of individual compensation, as well as its periodic readjustment, mainly consider one’s previous compensation, the criticality of the position, performance and achievement of established targets, the need for shielding, internal equity (including that of gender and race), the comparative analysis with the market, through salary surveys conducted by specialized consulting firms, as well as the competitive scenario. 2) Variable compensation Variable Compensation aims to reward the achievement and surpassing of the Company’s targets, aligned with the budget, strategic planning and market practices. Through this instrument, the aim is to achieve / exceed the targets and objectives of the organization defined in the threeyear industrial plan presented to the market. The variable component is subdivided into three groups: - The Short-Term Incentive Program called “MBO – Management By Objectives” – which is the short-term variable compensation program, based on the concept of profit sharing, linked to strategic indicators for the Company’s business, containing targets and objectives, both corporate and functional (for each Board); - the Bonus (una tantum) which is an instrument based on valuing individual performance, which can be used to recognize the outstanding performance of the executive, as well as rewarding the results of specific and relevant initiatives and projects for the Company; e - Long-Term Incentive, which is a share-based plan with the following objectives: (a) align the interests of senior management with the interests of shareholders, through participation in the business risk; (b) implement an integrated incentive system, aiming to balance the time horizon Classified as Public and the nature of the objectives; (c) increase the competitiveness of the recognition package and (d) operate as an instrument for retaining key people for the Company. 2.1) MBO The variable compensation of the Executive Board is directly linked to the evolution of performance indicators of interest to the issuers. Based on this, we align and link the interests of Officers to the Company’s results. The program’s structure is divided into Corporate Objectives, which have the following definitions: - Corporate objectives (with a total weight of 100% in 2025): the Company’s macro objectives, with high strategic relevance, which depend on the collective efforts of all the Company’s employees to be achieved. The performance indicators that are considered when determining the corporate objectives of the incentive plan are the main financial and operational indicators and ESG indicators: Net Promoter Score (Customer Loyalty Index), employee engagement and electricity from renewable sources, reassessed and validated annually, always in line with the objectives presented to shareholders for the Three-Year Plan. Such objectives are proposed annually by the Company’s management in accordance with the challenges of the Industrial Plan, and approved by the Board of Directors, upon recommendation of the Compensation Committee. Each objective is assigned a weight and three target levels, which correspond to 3 payment levels (currently set at 50%, 100%, and 150%). All objectives are paid individually and eligibility triggers may apply. Objectives with attainment below the minimum target of 50% do not generate payment and those with attainment above the maximum target have their payment limited to 150%. For each MBO – Management By Objectives participant, a target value is defined based on a salary multiple or amount of fees and its amount considers the importance of the occupant’s role within the organizational structure, based on the Total Compensation market parameters, identified in specialized surveys market. 2.2) Bonus (una tantum) The bonus is based on valuing individual performance, which justifies the company’s recognition, especially considering tactical initiatives and specific and relevant projects. The application of this instrument is linked to a salary multiple, the payment amount of which may vary according to the strategic role, the individual’s performance based on the relevance of a given project, initiative and / or financial / qualitative return for the Company, in line with the market’s Compensation Practices. 2.3) Hiring / Retention Bonus The Company, when analyzing the market conditions, context and challenges of the business and aiming to guarantee the continuity of the business and compliance with the Company’s strategic plan, can offer the payment of specific bonuses to ensure the hiring and / or retention of key executives. In the specific case of Hiring Bonuses, this modality aims to make it possible to make offers that are more attractive to external candidates and that minimize any occasional losses that may exist in the transition between companies. The value of the hiring / retention bonus is defined as an amount of fees / annual salaries, in line with market practices and proportional to the required retention period. In the case of Hiring Bonus, it may also vary depending on the particularities and specific conditions involved in the negotiation between the parties. 2.4) Long-term incentive plan: For each participant, a target value is defined based on a salary multiple, which is converted into a target number of shares. Such amount considers the importance of the occupant’s role within the organizational structure, based on the Total Compensation market parameters, identified in specialized market surveys. Classified as Public The Long-Term Incentive Plan establishes general terms and conditions for the granting Company’s shares, by senior managers and those employees who hold key positions in the Company, as approved by the Board of Directors and recommended by the Compensation Committee, based on proposal by the Chief Executive Officer and the People, Culture & Organization Officer. 2021-2023 and 2024-2026 Plans: On March 30, 2021 and March 28, 2024, the Annual Shareholders’ Meeting of TIM S.A. approved the long-term incentive plans, “2021-2023 Plan” and “2024-2026 Plan”, respectively, granted to senior directors and to those who occupy key positions in the Company. Before submitting the analysis and approval of a new plan, a market analysis is carried out to assess the need to update the current rules, considering the type of plan, eligibility criteria, general rules and the impact on the Total Rewards mix of eligible participants. The Long-Term Incentive Plans (“Plan”) provide for the granting of shares to participants issued by the Company and provide for a combination of two modalities: - Restricted Shares, subject to the participant remaining with the Company for a certain period; e - Performance Shares, subject to the achievement of specific targets and the participant remaining with the Company for a certain period. Generally, performance objectives are linked to economic/financial indicators and equity performance metrics (for example: Total Shareholder Return) and ESG indicators - Environmental, Social & Governance - (example: % of women in leadership positions, Ecoefficiency, % of black people in leadership positions and Recycling of solid waste), always in line with the objectives presented to shareholders for the Three-Year Plan. The number of shares may vary, for more or for less, as a result of the performance and possibly of the dividend award, considering the criteria provided for in each Grant. The term of validity of 2021-2023 and 2024-2026 Plans has the same periodicity of 3 years related to its vesting. In turn, in addition to considering the transfer of Shares, also provides for the possibility of making payment to participants of the equivalent amount in cash. As approved by the Company’s General Meeting of Shareholders, the Plans are managed under the responsibility of the Board of Directors, subject to the Company’s Articles of Organization. The shares granted under the terms of the Plan, including those already granted or not, and discounting those canceled, are limited to a percentage of the total number of shares issued by the Company during the term of the Plan, defined in the Plan’s regulations and approved at the General Shareholders’ Meeting. The Plan’s management is incumbent upon the Board of Directors, which may delegate the assignments specified to the Compensation Committee, subject to the terms of the Plan and the limits provided for by law and in the Company’s Bylaws. The base price of the share, for the purpose of calculating the amount to be granted to each Participant based on their award, considers the average price of the share, weighted by the financial volume, during a period defined by the Board. The amount of shares awarded is calculated according to the market price by dividing the target reward by the base share price. Performance conditions may also vary the number of shares granted, for more or less, depending on the criteria defined in each Grant. The performance measures defined for the Grants of the 2021-2023 Plan are broken down into an internal financial target and an external target for relative share performance, considering the TSR of the Company’s shares compared to the performance of the IBrX-50. Both were linked to an award table with a minimum variation of 75% and a maximum variation of 150%. In case of non-achievement of the minimum target of the internal indicator, no award is generated for the Vesting determined. In turn, the external indicator makes it possible to accelerate the result of the Classified as Public internal indicator, when reached, by up to +50 pp beyond the 150% limit, and it can slow down the minimum award of 75% by 25 pp. In addition, in this Plan we have included ESG targets during the 3 Grants, acting as a bonus or penalty +4%/-4%. The final award calculated according to the results of the internal target, the external target and the ESG target can reach a maximum of 204% payout. The performance measures defined for the Grants of the 2024-2026 Plan are broken down into an internal financial target (operates as the reward basis) and an external target for relative share performance (operates as an accelerator/decelerator), considering the TSR of the Company’s shares compared to the performance of the IBrX-50. The internal financial target is associated with an award table with a minimum variation of 50% and a maximum variation of 150%. In case of non-achievement of the minimum target of the internal indicator, no award is generated for the Vesting determined. In turn, the external indicator makes it possible to accelerate the result of the internal indicator, when reached, by up to +50 pp, and it can slow down the minimum award by up to 25 pp. In the 2024 and 2025 Grants, an ESG target was assigned acting as a bonus or penalty +4%/-4%. The final award calculated according to the results of the internal target, the external target and the ESG target must not exceed the maximum payout limit of 150%. 2.5) Clawback Policy Participants in Variable Compensation Programs will be subject to the Clawback Policy approved by the Board of Directors on November 6, 2023. This Policy provides for recovery of compensation in the event of a restatement of financial statements resulting from material failure to comply with financial reporting requirements under U.S. federal securities laws in accordance with the terms and conditions set forth therein. It is intended to comply with the requirements implemented by the SEC (Section 10D of the Exchange Act and Section 303A.14 of the NYSE Listed Companies Manual - “Listing Rule”). The full Clawback Policy is available for consultation on the Investor Relations website at: https://ri.tim.com.br/esg/regulamentos-e-politicas. In addition to the conditions provided for in the approved Clawback Policy, the Company may also recover any prize resulting from these programs that were, in whole or in part, obtained due to any type of error, fraudulent behavior or misconduct attributable to the participant, without which the same performance-related prize would not have been achieved or would have been achieved at a lower level. The activation of the Clawback does not exclude the Company's right to indemnity for any additional damages, nor in any way excludes the possibility of new initiatives, such as disciplinary measures, termination and/or any other lawsuit whatsoever permitted and provided for in accordance with current legislation. In this sense, the possibility of activating the Clawback is an additional element and not a replacement for other actions that can be triggered by the Company. The total amount that can be claimed for recovery corresponds to the difference between the net amount recognized as a performance-based award and the net amount that would have actually been achieved in the absence of the fraudulent behavior/misconduct/error. The activation of the recovery request may or may not be linked to a restatement of the financial statements, depending on the characteristics of the triggering event. In cases where it is necessary to restate the financial statements, the recovery will apply to all participants in the Programs, regardless of whether they gave rise to such recovery. In cases where fraudulent behavior / misconduct / error does not require restatement of the financial statements, the Board of Directors undertakes to decide whether the activation of Clawback will cover all participants who shared the same objective or only those who caused its activation. To activate the Clawback, the Board of Directors must first offer the Participant in question the possibility of requesting to be heard by the Compensation Committee, which will report the result of the hearing to the Board of Directors. If the Board of Directors deems it appropriate to proceed with the activation of the Clawback Policy, the Company will communicate the amounts recovered to the Participant in question in writing so that he or she can proceed directly with the refund within 90 days. After this period, without the Participant in question having directly refunded the indicated amount, the Company may order the recovery of the relative amount by deducting them from future payments or even through a lawsuit. Classified as Public This policy may be activated in the three years following the calculation or disbursement of the award subject to this action or fiscal year, whichever is older. The Clawback Policy can be activated even if the respective Participant has, at the date of the activation decision, interrupted - for any reason, including retirement - the employment relationship with the Company. 3) Direct and indirect benefits: 3.1) Private pension The Company has a private pension plan with Icatu/Onze, which guarantees the same conditions for the Company’s senior management as for other participants. This plan was launched in October 2023 and allows its participants to make the value of their contributions flexible by up to 15% of the nominal salary for participants in the Flexible Benefits program, and up to 5% of the nominal salary for other participants. For such contribution, the employee must contribute at least the same amount. As for the possibility of early redemption, this can occur in the following cases: - In cases of disability or death, the beneficiary or his/her dependents will receive 100% of the accumulated fund; - At any time, the participant can redeem his/her part of the contribution. However, the company’s portion is deducted in equal proportion to the participant's portion redeemed (except in cases where the participant has already reached 100% of the vesting table in Icatu/Onze, in which he or she is allowed to redeem the amount without deductions or grace periods beyond those already provided for in legislation on the topic); - Upon termination of the relationship with the Company, the participant can access the company’s part, up to the limit of 100%, in accordance with the vesting rule, which considers a proportional release based on the contribution time (installment linked to the accumulated balance of Itaú plan, a plan before the Icatu/Onze plan) or on the company’s time (installment linked to the accumulated balance of Itaú/Onze plan). It is worth highlighting that the Company’s Private Pension Plan does not cover the members of the Board of Directors and the members of the Fiscal Council. 3.2) Benefits Package The Company has a wide benefits package for Senior Management, where TIM offers, according to the established eligibility criteria: bank benefits, agreements, extended maternity leave, extended paternity leave, extended marriage leave, company time off, health care plan, pharmacy assistance, dental plan, life insurance, child nutrition assistance, daycare assistance, assistance for children classified as PwD, guidance and personal support program, food/meal vouchers, education reimbursement and quality of life. This benefits package evolves according to market practices and the collective agreement. The benefits package for each member of Senior Management considers the importance of the occupant’s role within the organizational structure, based on the Total Compensation market parameters identified in specialized market surveys. • main performance indicators considered therein, including, where applicable, indicators linked to ESG issues Fixed Compensation: Market practices are the factors considered in determining value, in addition to individual performance and achievement of established targets.

Long-term incentive plan - 2021-2023 and 2024-2026 Plans: The shares are granted according to the achievement of a set of performance measures and according to the participant’s permanence in the Company for a certain predefined period. The plan’s performance measures consider internal economic/financial indicators, external relative performance indicators (the Company’s position in a TSR ranking made up of companies that make up the IBrX-50) and ESG indicators. ii. reasons that justify the formation of compensation The compensation breakdown considers the importance of the occupant’s role within the organizational structure, based on the Total Compensation market parameters, identified in specialized market surveys. The elements of Fixed Compensation, Variable Compensation and Benefits are weighted by the organizational evaluation of positions, through an internal system that classifies positions into “bands” based on the Hay methodology (a system with which the main positions in the organization are evaluated). The Company’s short, medium and long-term compensation components are based on financial results, which act as a parameter for defining the limits of variable compensation and the share-based plan, ensuring equality between results and bonuses for the Company’s executives. iii. the existence of members not compensated by the issuer and the reason for this The Company has five members of the Board of Directors who are not compensated, as they expressly waived the fixed monthly fees in the year 2025. d. existence of compensation supported by subsidiaries or direct or indirect controlling shareholders The Company has 5.0 members of the Board of Directors who are remunerated by the indirect controlling shareholders. The other members of the Statutory Executive Board, of the Board of Directors and of the Fiscal Council, when compensated as a result of activities performed for the Company, have their compensation fully borne by TIM S.A. e. existence of any compensation or benefit related to the occurrence of a certain corporate event, such as disposal of issuer’s controlling interest The Company does not define as a rule the compensation or benefit linked to the occurrence of a corporate event. However, it can establish a Hiring / Retention Bonus or link certain performance objectives in its variable incentive instruments to those who act directly with the challenges associated with the corporate movement, thus enabling the fulfillment of the strategic plan and the creation of value for shareholders. Finally, for the Share-based Long-Term Incentive Program, the possibility of the Board of Directors revising it is provided for, taking the necessary measures to allow its continuity, including its replacement by similar instruments, to avoid any distortions and losses to the Participants, the Company and its Shareholders, in strict alignment with its objectives.

Regarding the share-based compensation plan of the Board of Directors and the Statutory Executive Board in force on the last year and provided for the current year: a. general terms and conditions At the Extraordinary General Meeting held on March 30, 2021, a new long-term incentive plan was approved for the 2021-2023 fiscal years. The Plan approved proposes to compensate participants with shares issued by the Company, subject to certain Restricted Shares and/or Performance Shares. Under the Plan, the Company’s officers and employees (“Participants”) are eligible to receive shares issued by us upon execution of a share granting agreement (“Stock Granting Agreement”), which must specify: (a) the number of shares object of the grant; (b) general conditions of performance and grace period for acquiring the right to receive shares; (d) the performance factors and how they may change the number of Performance Shares awarded and (e) the number of shares that will be subject to the Share Ownership Policy. The number of shares may vary, for more or for less, as a result of the performance and possibly of the dividend award, considering the criteria provided for in each Grant. Generally, performance objectives are Classified as Public linked to economic-financial indicators and equity performance metrics (for example: Total Shareholder Return) and ESG (Environmental, Social & Governance) indicators, always in line with the objectives presented to shareholders for the Triennial Plan. On March 28, 2024, the General Shareholders’ Meeting of TIM S.A. approved a new long-term incentive plan for the years 2024-2026, whose Regulation contains the same characteristics as the 2021-2023 Plan mentioned above. The Share-Based Long-Term Incentive Plans are managed by the Board of Directors, with the support of the Compensation Committee, following the terms of the Plan and the limits established by law and our Bylaws. b. approval date and responsible body The Company has submitted to the competent corporate bodies a new plan for the Long-Term Incentive Program for the 2021−2023 fiscal years. The Plan was approved at an Extraordinary Shareholders’ Meeting held on March 30, 2021. A new long-term incentive plan for the years 2024-2026 was approved on March 28, 2024 by the Annual Shareholders’ Meeting of TIM S.A. c. maximum number of shares covered The shares granted under the terms of the Long-Term Incentive Plan, including those already received by the participants or not, minus those canceled under the terms of the Plan, may grant rights on a number of shares that does not exceed 2% of the total number of shares issued of the Company during the Plan’s effectiveness, provided that the total number of Shares issued or likely to be issued under the terms of the Plan is within the limit of the Company’s authorized share capital. d. maximum number of options to be granted Not applicable, as TIM S.A. does not have a call option plan in force. e. conditions for acquisition of shares The conditions for acquiring shares, as provided for in the Plans, are described in the Stock Granting Agreement entered into with each of the Participants. To be entitled to receive the shares granted as Restricted Shares and/or Performance Shares, the beneficiary must wait a maximum period of 90 days, after the end of the Company’s grace period, to transfer the shares, provided the applicable performance and grace period conditions are met. f. criteria for setting the acquisition or strike price The Plans defined for 2018-2020 and 2021-2023 allow TIM managers and/or employees to receive payments in shares issued by the Company, subject to certain Restricted Shares and/or Performance Shares . The base price of the shares granted in the 2021−2023 and 2024−2026 Plans set by the Board of Directors, have the recommendation of the Compensation Committee and do not include criteria for setting the acquisition price, as they grant shares at market value, under the rules below: (i) Measurement Period of the Share Base Price: period, to be set by the Board of Directors, prior to the Share Granting, for defining the Share Base Price; Classified as Public (ii) Share Base Price: average price of the Shares, weighted by the daily financial volume traded at B3 (B3 S.A. – Brasil, Bolsa, Balcão) during the Measurement Period of the Share Base Price. g. criteria for setting the acquisition or strike term For the 2021-2023 and 2024-2026 Plans, as they are stock grant plans and not options, there is no exercise term defined. h. form of settlement For the 2021-2023 and 2024-2026 Plans, there is no stipulated form of settlement, as there is no procedure for acquiring shares since the Plan provides for the granting of shares at market value. The Board of Directors has the option of making the payment in shares or its equivalent in cash. i. restrictions to the transfer of shares The Board of Directors, in its role as administrator of the Plans, shall follow the best governance practices and the rules restricting the transfer of the shares issued by the Company that have been granted. The Board of Directors is also entitled to establish Stock Ownership Guidelines. j. criteria and events that, when checked, will cause the suspension, change or extinction of the plan Without prejudice to the provisions of the Plans or any of the Stock Granting Agreement, the shares granted under the terms of the Plans will automatically expire, ceasing all their effects by operation of law, in the following cases: (i) upon full receipt of the shares provided for under the 2021−2023 and 2024−2026 Plan grants; (ii) upon termination of the Stock Granting Agreement; (iv) if the Company is dissolved, liquidated or declared bankrupt; (v) at any time at the discretion of the Board of Directors or whenever there are situations that, under the terms of the law or regulations in force, restrict or prevent the trading of shares by Beneficiaries/Participants; e (vi) in the event of termination of the Beneficiary/Participant described in item “k” below. k. effects of the removal of the officer from the issuer bodies on its rights provided for in the share-based compensation plan If the Participant requests resignation from the Company, the right to receive the ILP (Long-term Incentive Plan) that has not completed the vesting period on the termination date will be automatically extinguished, by operation of law, regardless of prior notice or indemnification. In the event of Termination by decision of the Company without just cause (or without the occurrence of facts that would constitute just cause if the Participant were employed by the Company), or by mutual agreement, the right to receive the LTI that has not completed vesting on the date of termination will be in proportion to the vesting actually completed, by dividing the total months completed by the total months comprising the vesting, considering as a “month” the period of 30 calendar days, provided that the Participant has completed at least 12 months of participation in the Plan. Classified as Public In the event of Termination by decision of the Company with just cause (or with the occurrence of facts that would constitute just cause if the Participant were employed by the Company), the rights to receive the LTI will be automatically extinguished, by operation of law, regardless of prior notice or indemnity. In the event of the Participant’s death, his/her heirs and successors shall receive the LTI that has not completed vesting in full (considering 100% achievement of the performance conditions for the remaining period) in cash, regardless of whether vesting has been completed. In the event of the Participant’s retirement, making it impossible for him/her to carry out his/her activities in the Company, the Board of Directors may authorize the receipt of all or part of the Shares subject to this Instrument, regardless of vesting. The Board of Directors may determine that the Termination will not have occurred in the event of the Participant being transferred to another company in the same conglomerate as the Company (understood as any direct or indirect parent company of the Company, associated company, subsidiary or a company subject to common control) and determine specific rules for dealing with such cases. 8.5.

I. if there is the possibility of early redemption and conditions In this plan, all employees are eligible and can join the benefit at any time, considering the rules in force between TIM and Icatu/Onze. Classified as Public As for the possibility of early redemption, this can occur in the following cases: • In cases of disability or death, the beneficiary or his/her dependents will receive 100% of the accumulated fund; • At any time, the participant can redeem his/her part of the contribution. However, the company’s portion is deducted in equal proportion to the participant's portion redeemed (except in cases where the participant has already reached 100% of the vesting table in Icatu/Onze, in which he or she is allowed to redeem the amount without deductions/taxes or grace periods beyond those already provided for in legislation on the topic); • Upon termination of the relationship with the Company, the participant can access the company’s part, up to the limit of 100%, in accordance with the vesting rule, which considers a proportional release based on the contribution time (installment linked to the accumulated balance of Itaú plan) or on the company’s time (installment linked to the accumulated balance of Itaú/Onze plan). This percentage scale starts with three years working for the company at 30% and, after 10 years, it offers the possibility of redeeming 100% of the company's value. 8.15. In the form of a table, in relation to the last three years, and in relation to the Board of Directors, the Statutory Executive Board and Fiscal Council, state: 8.16. Describe contractual arrangements, insurance policies or other instruments that constitute compensation or indemnity mechanisms to the directors in case of removal or retirement, informing the financial consequences to the Issuer For the members of the Board of Directors and the Fiscal Council, when installed, there is no provision in the contract or other mechanism that grants additional compensation or indemnification in case of removal from office or retirement. For members of the Statutory and Non-Statutory Executive Board, their contracts may or may not provide for additional compensation or indemnification in the event of termination, corresponding to the amounts and conditions, of a legal or complementary nature, to be paid in the event of termination of the term of office or termination of the employment relationship with the Company. Legal termination amounts are calculated and paid by the company in accordance with current and applicable legislation for each type of termination. Eventual amounts and additional termination conditions are defined based on market practices, considering the different termination modalities. The position involved, the Executive’s tenure in the Company, the context and conditions under which the terminations are being carried out are also factors that affect this definition. In general, such compensation is related to non-competition agreements and/or early termination of contracts. Contracts may also provide for ways of settling variable compensation that on the date of termination do not yet have the result of their objectives available.
